Practical Standalone Tuning: Step 2: Trigger Setup
Step 2: Trigger Setup

00:00 | - The next step of the process is to have a look at our trigger setup so that the ECU's getting the correct information from this particular engine and it knows what the RPM and engine position is. |
00:12 | So in the PC Link software if we go through to the triggers menu and we look at trigger setup. |
00:18 | this is where we can choose what particular trigger mode we want to use. |
00:24 | Now you can see we've already got this set to BMW M52 which is the particular trigger mode for this engine. |
00:31 | If you cycle through though here you can see all of the different modes that Link make available to suit the common engines that they've already decoded. |
00:42 | So if you've got one of these supported engines, it's really easy, you just click on the correct one, and basically everything will be preconfigured. |
00:51 | So we start with that by choosing BMW M52. |
00:54 | But if we go back and have a look at what else is available in this menu, you can see we've got trigger one, and we've got trigger two. |
01:03 | If we click on trigger one, so this is our RPM sensor, this is giving us the engine RPM. |
01:10 | And in this case we've got our trigger type, which is set to optical or hall. |
01:16 | And we've got a filtering level here which is set at level one which is low. |
01:22 | We would want to start with that low level of filtering unless we really needed to go any higher. |
01:27 | With a hall sensor, we generally need that pullup resistor on that particular channel turned to on. |
01:34 | And we've got the option of triggering on either a rising or a falling edge. |
01:39 | Now this information will generally be set up when you choose that trigger mode. |
01:45 | Or in the case of an engine that you're not familiar with, you can get the advice on how to set this up from the ECU manufacturer. |
01:53 | In this case though, these are the correct settings for the BMW M54 engine. |
01:59 | So let's just have a look though at trigger two, and we've got the same settings here. |
02:06 | So again we've got a hall sensor, optical hall sensor, we've got our level one low filtering, and the pullup is still turned on, and we've got a falling edge trigger. |
02:20 | So that's basically everything there set up for the triggering system. |
